G. H. KERN METHOD OF PRODUCING MOTION PICTURES 2 Sheets-Sheet 2 Filed Oct. 19, 1921 unis invention relates to s. new and useful method of producing motion pictures or positives s holder therefor. I

The ohje ts of the invention are to produce pictures or pQ-l ives which can be arranged cum-fer tially on suitable holder m eech icture or positive can he sequen presc ted to the projecting means so the entire surface each With the ioregoing and other objects in- View, invention consists in certain novel features hereinafter more fully described and claimed and illustrated in the accompanying drawings, in. which Figure 1 shows the insnner in which the pictures are projected onto a screen.

Figure 2 is s top plan View of the holder with the pictures in position therein.

Figure 3 is a fragmentul View of a strip containing a series of positives or pictures utilized in projecting pictures for the holder.

Figure t is a plan View partly broken away of a plate on which the pictures or positives have been reproduced in a reduced form, said plate being" rezidy to be cut into strips for positioning in the holder.

Figure 5 illustrates tragmentsl views of portions of the strips.

Figure 6 is a side elevationul View, partly brokeneway, oi the up per end. of the holder.

Figure 7 is aside elevational View partly broken away of the lower end of the holder.

Figure 8 is a horizontal cross-section taken on line 8--8 of Figure 7.

Figure 9 is a detail sectional View of the lower end of the holder showing means for adjusting the strips in position.

Referring loy numerals to the accompanying drawings, 10 indie-s tes a source of light positioned in front of which is a condensing lens 11. 'lhis lens is positioned to one side of a holder 12, which latter is formed of a series of bars 13 held in spaced relation by loose ring 14, to which the lower ends of DELAV said loars are secured,

Project lenses are arranged in the inner side c container and in uiignnient with a source of light 10 end condensing lens ll. The image ofthe picture projected forwardly by lenses 20 is received by reflecting member 221 which is spaced from. said projecting lenses and angularly disposed so as to reflect the image against at reflecting member angularly disposed above holder 12, end in co-operative relation With reflectlug: member 21.

A screen 523 of translucent material is located in the upper portion of housing 18 and in horizontal alignment with reflecting member 22. The image is reflected by member 22 and is projected in enlarged t'orm against screen" lln order to form strips 19 in a practical and efficient manner, the original negatives are produced by having; the camera tilted at afortylive degree angle so that the pictures will be disposed horizontally on the celluloid strip at right angles to the line of travel thereof. Positive pictures arc printed from these negatives on strips oiiconi'enient length-An the p esent instance, strips containing screntv-l 12 pictures each. i portion of one or said strips is illustrated in igure 3 and the position of the pictures is indicated thereon by A, B, C, D and E. The strips are then secured to a plate in proper sequence reading from right to. left and from top to bottom. This muster plate is then reproduced in a reduced form on a transparent plate 25, in which the first hori- *zontal row of pictures is represented by the row. all of said rows containing the This sha same number of pictures and all of said pictures being aligned in horizontal and vertical directions, as indicated by the horizontally disposed solid lines 26 and vertically disposed dotted lines 27. This plate is then cut along dotted lines 27 into vertical strips 19, as indicated 28 in Figure 5. lhe pictures will be horizontally disposed on the strips and will be in vertical alignment with each other but in point of sequence will be seventy-five exposures apart, or the number of strips into which divided.

In Figure 5, strip a will contain pictures Nos. 1, 76, 151, 225 and so on down. trip I) will contain pictures Nos. 2, 77, 152, 227 and so on. Strip 0, assuming this to be the last strip formed from plate 25, will contain pictures Nos. 75, 150, 225, 300, etc., reading downwardly. The upper end oi each strip is left blank, as indicated at 2.9, in order to provide suitable clearance in positionin the strips in the holder 12.

Base ring 14 is provided with steps or.

spacers 30 which vary in height, the dirierences between any two spacers being equal (in the present instance) to one-sev enty-fifth of the height of one picture, the

spacer for the strip containing picture No.- 1 being highest andthe spacer containing wise, strip l; occupies a position to the'right v of strip a, and strip 0 occupies a position to the left of strip 0;, as shown ini igures 6 and 7. Thus, it will be seen that picture No. 75 relatively occupies the same position to picture No. 76 as picture No. it occupies with respect to picture No. 2, each strip being ofiset 'with respect to its adjacent strips the proper distance by its corresponding spacer 30. In this manner, the entire series of pictures is arranged in ahelical form on the container, and by moving holder 12 a proper distance upwardly every time a picture is positioned between lenses' vided with a plate 32 which forms a stop or rest for the lower end of a strip 28, when the latter is positionedv therein.

By turnng screw 31, each strip can be adjusted to its proper position with respect to its adjacent strips. v i a By mal'hg the holder 12 in the form of a,

a hollow drum which is open atvitsiupper end, the projecting-lenses 20 and reflecting member 21 'ehn be accommodated within plate 25 has been said holder as the same moves upwardly, thereby reducing the'size of the motion picture, and by -forming pictures with positives on transparent strips 28, pictures can be projected onto reflecting member 21 which occupies a position within holder 12 and each picture being formed on a flat surface will, when projected onto screen 23, be properly focused.

The pictures made according to m I invention are designed to be accurately p aced in position on the holder and the latter can be interchangeably used on a number of motion picture machines.

Obviously, various changes in the size and form of the strips and the holder can be made and substituted for those herein shown without departing trom the spirit or my invention.

What 1 claim is: I

lufi' method of producing motion pictures consisting of arranging the pictures sequentially in horizontal and vertical rows on a plate, then dividlng said plate into' vertical strips in line with said vertical rows, and then placing said strips in their sequential relation in the circumference of a suitable support whereby the entire surface of each picture occupies a position at right angles to the line of projection.

2. A method of producing motion pictures consisting in arranging pictures ona transparent plate in their proper sequence in a series of horizontally disposed rows whereby the pictures of each series are in vertical alignment with the corresponding pictures of the remaining series, then cutting said plate into strips along the l1Z18S'O the vertically aligned pictures, and then arranging said strips in their propersequence circumferentially on a proper holder.

3, The herein described method of producing motion pictures consisting of arranging pictures sequentially in a series of rows, whereby said pictures will be aligned at right angles to said rows, then dividing said plate at right angles to said rows into strips containing said aligned pictures, and then arranging said strips circumferentially in a holder, vwhereby each strip is lon itudinally offset with respect to its adjacent strips and the pictures are arranged sequentially in a helical form.

4. The herein described method of producing motion pictures consisting in arranging pictures sequentially in serles of hori-' zontally disposed rows whereby the pictures of each row are in vertical alignment with the pictures of the adjacent rows, then severing said plate vertically to form strips containing said vertically aligned pictures, and then arranging said strips in the periphcry of a suitable holder'wherebysaid pictures are arranged in their proper sequence in aihelical form.

The herein described method of producing motion pictures consisting in transferring positives on a transparent plate in series of horizontal and vertical rows, the positives in each horizontal row being arranged in sequence and said horizontal rows being sequentially arranged with respect to each other, then cutting said plate into strips along said vertical rows, then arranging said strips in their proper sequence on a suitable holder whereby each strip is ottset with respect to its adjacent strips so that all of said positives are sequentially arranged on the circumference of said holder.
